We are now able to find out what kind of power is being used by our test system and the associated graphics cards installed. Keep in mind; it tests the complete system (minus LCD monitor, which is plugged directly into an AC wall socket).
The H55M-ED55's power draw from the wall is very low. Even when under full load the board did not pull over 83 Watts. This was lower than the next closest board by 7 Watts.
As a new measure, we are now monitoring the heat generation from the key components on the motherboard; this being the Northbridge, Southbridge (if it contains one) as well as the Mosfets around the CPU. The results are recorded at idle and load during the power consumption tests.
The H55M-ED55 did generate more heat than the other boards, but this has more to do with the minimal heatsink over the chipset than power running through the system.
